Did any of the '81 Delorean's come from the factory with the radio antenna built into the windshield? Of all the '81's that I have seen, most have had theirs mounted on the right front fender, or if they were moved, have that button whole plug in the fender. My 81 has no fender whole and an antenna incorporated into the windshield. P.S. A special thanks to DMC Joe for welcoming me aboard.
